Hi @sgvandijk . I just stumbled upon this answer and I have two little questions about it: 1. I didn't understand the di

I would like to implement a ROS Node that manages multiple objects which each have their own subscriptions. Now for an object to have its own subscriptions the class needs to inherit from rclcpp::Node. So is it possible to have to compile two different classes that both inherit from rclcpp::Node in one executable or does this break ROS 2 design rules?

In the ROS manual/wiki you can see, that ROS is only made for C++11. But what exactly does that mean? What happens if I just put add_compile_options(-std=c++17) in the CMakeLists.txt of my ROS-package and use C++17-features anyway? Specifically: Is it possible to use parallel std::for_each from C++17 in my ROS-nodes?
